I have purchased lines from $10 to $99 and while the more costly lines are almost always a notably better line, they are not worth the extra money for most of my fishing. I will generally load up on closeout lines at the end of the season. In addition, I have had good success with lines purchased from Hook & Hackle and Old Tyme Fly Fishing. I especially favor Old Tyme Fly Fishing's Magalloway floating lines, but the lines are DT which is not to everyone's liking.
